Application filed April 13, 190%. Serial No. 203,012. ilo model.)

T!) (all whom it may (lo/morn:

Be it known that l, OwnXJ. TRAVIS. a citi- Zen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful improvements in Derailing Devices, of which the following is a specification.

My invention pertains to derailing-frogs, and is designed more particularly as an improvement upon the derailing devices constituting the subjects of my Patents No. 479,338, of July 19, 1892, and No. 5312-118,

- of April 9, 1895.

The novelty, utility, and practical advantages of the present invention will be fully understood from the following desc""n*"' and claims when taken in connection \vi accom )anyin drawin s, formin iart of this a z: z:

specification, in which Figure l is a plan view of my novel frog in its proper operative position relative to a railway-rail; and Fig. 2 is a view showing the frog in full lines in its proper operative position relative to the rail and in dotted lines in its idle position, the rail beingin transverse section.

Similar letters designate corresponding parts in both views of the drawings, referring to which A is a railway-rail.

B is a sleeper or tie on which the rail is secured.

(l is an eye secured on the up er side of the sleeper at one side of the rail A.

D is a frame fixed. on the upper side of the sleeper at the opposite side of the rail with reference to the eye C and made up of a base a and standards 6, and E is my novel frog; As clearly shown in Fig. 2, the standards 6 of the frame D are bypreference of a slightly less height than the rail in; also, the frog E is provided with a depending end portion 0, disposed between and pivotally connected to the standards 6, preferably through the medium of a transverse bolt (Z. The said frog is also provided with a shoulder 0, arranged to bear against one side of the head of the rail A, a portion 7, arranged to bear on top of the rail and having the flange r on its upper side, and an apertured lug it, arranged,

by preference, on the free endof the frog. The said lug ]t is for the connection of a link F, which when the frog is in the position shown by full lines is designed to be locked to the C, so as to prevent a mischievous person from throwing the frog oil" the rail.

it wil be readily appreciated from the foregoing that when my novel frog is in the position shown by full lines relative to the rail i will cover the rail without liability of breaking same and will serve eiliciently to derail a car. It will also be appreciated that when the frog is thrown into its idle position, as shown by dotted lines in Fig. 2, it will by v'rtuc of its end 0 rest in a horizontal plane entirely below the upper side of the rail, and hence will oll'er no obstruction, which is an important advantage.

Hy novel frog is designed more particularly for side-track protection on exposed or hill sidings, but may also be used to advantage in interlocking plants or anywhere at derailing device is required.

it will he noticed that neither the frame or stand'l) or any other part of my novel device is connected to the rail, and hence the application of the device simply involves spiking the frame or stand to the sleeper B and connecting the eye thereto.

1 have entered into a detailed description of the construction and relative arrangement of the parts embraced in the derailing device constituting the preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and relative arra gemcnt oi. parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure by Letters Patent, is'

l. in a derailing device, the combination of a sleeper or tie, a railway-rail thereon, a frame or stand on the sleeper or tie, at one side of the rail, a vertiCally-swinging frog arranged when swung off the rail to rest entirely below the plane of the upper side of the rail; said frog being pivoted to the frame or stand, a link connected to the free portion of the frog, and means on the sleeper or tie at the opposite side of the rail, with reference to the frame or stand, adapted to be connected to the link.

In a derailing device, the combination of a sleeper or tie, a railway-rail thereon, a frame or stand arranged on and connected to the upper side of the sleeper or tie and disposed below the plane of the upper side of the rail, a Vertically -swinging frog having a downturned end (3 pivoted to the frame or stand, and also having a shoulder to bear against one side of the rail-head and the portion arranged to bear on the upper side of the rail-head and I 5 provided on its upper side with a flange y, a link connected to the free portion of the frog, and means on the sleeper or tie at the opposite side of the rail, with reference to the frame or stand, adapted to be connected to the link.

In testimony whereof I have hereunto set my hand in presence of two subscribing \vitnesses.
